In the APA style guide https://columbiacollege-ca.libguides.com/apa/journalarticle, it states

Capitalize only the first letter of the first word of the article title. If there is a colon in the article title, also capitalize the first letter of the first word after the colon.

So just to be clear, if the article title is "Sentiment Analysis of US Airline Twitter Data using New Adaboost Approach", do I downcase it myself and cite it as

Eswaran, P., Santhosh, M., Krishnan, A. H., & Kumar, T. (2019, April). Sentiment analysis of US airline twitter data using new adaboost approach. International Journal of Engineering Research & Technology (IJERT), 7, 1–3. ?
